Star Wars: Jedi Challenges is getting a free update called
"Lightsaber Versus Mode", which adds local multiplayer to the previously
single-player game, The
Verge reports. The update is available on the Google Play store, but it
also requires two of the Lenovo Mirage AR systems, two
headsets, two lightsaber controllers and two light-up tracking beacons set
to different colors. For this game, you can't "just hack
away at your opponent; it procedurally generates a battle, using familiar
elements from the single-player dueling mode".

The Arch Linux 2018.05.01 snapshot was released this week. This is the first
to include the Linux 4.16 kernel, with mitigations for Meltdown and Spectre,
updates for several drivers, improved KVM support and more. Note that this
snapshot is only for new deployments. (Source: Softpedia

Google today announced the release of version 0.1 of the open-source Kubeflow
tool, which is "designed to bring machine learning to Kubernetes
containers". According to TechCrunch, "the idea behind the project is to
enable data scientists to take advantage of running machine learning jobs on
Kubernetes clusters. Kubeflow lets machine learning teams take existing jobs
and simply attach them to a cluster without a lot of adapting."

Google also has open-sourced gVisor, a new way to sandbox containers to
"provide a secure isolation boundary between the host operating system and
the application running within the container", ZDNet
reports. gVisor's core is "is a kernel that runs as a
normal, unprivileged process that supports most Linux system calls. This
kernel, like LXD, is written in Go, which was chosen for its memory- and
type-safety".

According to The
Register, "researchers have unearthed a fresh new set of ways attackers
could potentially exploit data-leaking Spectre CPU vulnerabilities in Intel
chips". Currently, there is only information on Intel's plans for patches,
but there is evidence that some ARM CPUs also are vulnerable.
